The problem with anti-ballistics is that they aren't a perfect technology yet. They only have a ~50% success rate in live testing, last I heard. You do not want to stake your billion-dollar floating airbases on a coin flip.

Also, don't give me that "hurr-durr why don't they just fire more than one missile" crap. You try aiming more than one hundred-thousand dollar missile at a target moving at hundreds of miles an hour towards you without them smacking into each other or missing.

Surprised that I haven't seen Blacklight: Retribution here yet. It's a damn-nice looking Sci-Fi FPS with elements of Deus Ex and Crysis thrown in there. Great graphics, and not too far to the pay-to-win side of things.

Then I read the Wikipedia page and was disappointed. The term "hovercraft" is slightly misleading. It's actually a surface effect vessel, where the main (catamaran) hull is supplemented by an air cushion, allowing it to sit higher in the water and reach higher speeds.
